The flux agents in common mould fluxes were fluoride and sodium oxide, which would do great harm to environments. B2O3 was selected as flux. The physical properties of B2O3-containing mould fluxes were studied. The corresponding physical properties of 37. 91% CAO-43.09% SiO2-5% Al2O3-5% MgO-2% li20-7% B2O3 mould fluxes were as follows： the melting point was 909℃, the flowing temperature was 1 160℃, the viscosity and surface tension at 1300 ℃ were 0. 4 Pa · s and 0.32 N/m respectively, which could meet the demands for certain kinds of steels for mould fluxes in continuous casting.

It was first found that Ind(2)Y(mu -Et)(2)AlEt2 and Ind(2)LnN(i-Pr)(2) (Ln = Y, Yb) exhibit extremely high catalytic activity in the polymerization of methyl methacrylate. The reactions can be carried out over a quite broad range of polymerization temperatures from -30 to 50 degreesC. PMMA with high molecular weight (7.8 x 10(-5)) and high isotacticity (94%) can be obtained by using Ind(2)Y(mu -Et)(2)AlEt2, and narrow molecular weight distribution (M-w/M-n < 1.5) can be obtained by using Ind(2)LnN(i-Pr)(2) (Ln = Y, Yb).

AIM: To understand the mechanism by which anti-β4 integrin monoclonal antibody (mAb) inhibits apoptosis of vascular endothelial cells (VEC). METHODS: Viability was determined by counting the cells that attached to dishes after treatments. DNA fragmentation was analyzed by agarose gel electrophoresis and fluorescence microscopy. The intracellular content of cAMP was measured by radioimmunoassay (RIA). The levels of p53 and Ras expres- sions were analyzed by fluorescence microscopy combined with immunofluorescence under laser scanning confo- cal microscopy. RESULTS: After the cells were deprived of fibroblast growth factor (FGF) and serum were exposed to the mAb 5 mg/L for 24 h, the detachment and DNA fragmentation of these cells were suppressed. When cells were deprived of FGF and serum, the intracellular cAMP level and Ras protein content decreased (P<0.05), while the level of p53 protein expression increased (P<0.05). But in the presence of anti-β4 integrin mAb, VEC apoptosis was inhibited, and at the same time, the changes mentioned above were obviously blocked (P<0.05). CONCLUSION: Anti-4 integrin mAb inhibited apoptosis by affecting the level of cAMP, and blocking down- regulation of Ras protein and up-regulation of p53 protein in VEC.

随着我国外贸出口面临的反补贴调查情况剧增和中国完全市场经济地位的逐步确立,我国现存的某些产业补贴措施的影响,正在由潜在危胁转化为现实危害。进口国具备了同时使用"反倾销"与"反补贴"两种手段和其他的保障措施,来限制中国的产品出口的条件,给中国的出口企业带来了严重的影响。反补贴已经成为将WTO协议及相关规则融入我国法律体系和制定产业政策时必须加以认真研究的一个问题。

人们对社会信任困境的讨论多半从传统道德弱化或制度信任缺失入手。这固然有其合理之处,但问题在于:如果只是局限于此,却忽视信任困境发生的社会转型背景,那么就难以对信任困境有正确认知。就当前而言,无论是怀疑或不信任情绪,还是信任的功利化与污名化现象,抑或是信任修复困境,都与深度转型中不确定性的市场交往环境、"资本逻辑"诱导,以及道义型信任模式与制度型信任模式的脱节相关。因而,破解社会信任困境也需立足于深度转型实践,提高失信成本,完善市场运行机制,夯实信任的道德基础与制度基础,从而建构中国特色的信任模式。
